POST method is a request method supported by the HTTP protocol used by the World   Wide Web. POST request, an amount of data of any type can be sent to the server.The POST method does not have any restriction on data size to be sent. By using Secure POST method you can make sure that your information is secure.Since the data sent by the POST form method is not visible in the URL, so it is not possible to bookmark the page with a specific query.

These are the points is about the get how to work and process:-

  • POST requests are never cached.
  • POST requests do not remain in the browser history.
  • POST requests cannot be bookmarked.
  • POST requests have no restrictions on data length.
